5.3 Ethernet Access: Telnet and SNMP Protocols

The optional 10/100 BaseT Ethernet port provides Telnet- or SNMP-based monitoring and management.

The 10/100 Base T Ethernet management services card provides Telnet-based monitoring and management, including firmware update using FTP.

Remote system monitoring is also available using Simple Network Management Protocol (SNMP). An agent resides in the array which takes information from the Array and translates it into a form compatible with SNMP. If certain conditions arise, the agent sends asynchronous notifications (traps) to a client.

To connect to the Ethernet port

1Connect a cross-over cable (for a direct connection to a PC) or regular network cable from a network device to the optional RJ45 Ethernet port on the Ethernet management card on the front of the array.

2If using a direct connection, power on and boot up the host computer.

3Attach a DB-9 null modem serial cable (the cable must be no longer than three meters) from the RS-232 port of the array to a host computer and open a terminal emulator program on the host to set the Ethernet parameters. Turn on the array.

4First time use: Upon successful power up and diagnostics, set the host computer with the appropriate settings.

The host computer must have appropriate network settings to allow it to communicate with the array. Please see your system administrator for more information.

To use Telnet

1If you have not already done so, change the IP address from the default by first accessing the serial connection and changing it using the CLI.

Change the IP address to a network specific value or, if the local network uses DHCP, you may enable automatic IP addressing (set IPDHCP enabled) using the CLI.

2Open a Telnet session on the host computer.

• IP address

Port type: telnet

Terminal type: vt100

3If you make any changes to the network setting on the Diamond Array, use the SaveConfiguration and FirmwareRestart commands.

4Username/password: You will be prompted for a username and password, up to eight characters each, case insensitive. Only one username/password combination is available per array.

You may change the telnet username and/or password after entering a CLI session using the commands

set TelnetUsername [username] set TelnetPassword [password]

Or change the telnet username and/or password using the ExpressNAV interface Configuration page.

RestoreConfiguration default sets the telnet username and password to the default values.

The username default is telnet and password default is diamond.

5You should now be in the CLI. To see a list of available commands, type help at the Ready prompt or refer to this manual’s Index. Or, access the ExpressNAV interface (refer to

ATTO ExpressNAV: Browser-based Interface on page 25).

6Configure the unit as a JBOD, RAID Level 0, RAID Level 1, RAID Level 10 or RAID Level 5 array with or without hot spare sleds as described later in the manual.

To use SNMP

1Enter the CLI through the serial port or Ethernet.

2Change the IP address to a network specific value or, if the local network uses DHCP, you may enable automatic IP addressing.

3Set the number of trap client addresses by typing

set SNMPTrapAddress [1-6] [IPAddress] [Level]
